The study of human evolution involves many scientific disciplines‚ including physical anthropology‚ primatology‚ archaeology‚ linguistics‚ evolutionary psychology‚ embryology

Human Evolution Human Evolution‚ the biological and cultural development of the species Homo sapiens‚ or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa‚ Europe‚ and Asia. Tools of stone‚ bone‚ and wood‚ as well as fire hearths‚ campsites‚ and burials‚ also have been discovered and excavated. As a result of these discoveries‚ a picture of human evolution during the past 4 to 5 million years has emerged. Human Physical Traits Humans are

The history/evolution of computing predates silicon microchips and CPUs by hundreds of years. The modern computers we are all familiar with can trace their roots back to simple computational machines that seem far removed from what we think of as a computer today. Simple Computers • By definition‚ a computer is any device capable of performing mathematical equations or calculations. Therefore‚ many simple devices such as an abacus (which dates back to at least 300 BCE) or a slide rule (first

Evolution of the Earth The planet earth has gone through much abuse and punishment in the past. Formed approximately 4.5 billion years ago‚ the earth has undergone multiple catastrophic asteroids erasing species after species. Due to geologic evidence‚ it is estimated over 90 percent of all life that had ever lived in this planet have been extinct. No more than the past 500 million years alone‚ 50-90 percent of all organisms on earth were wiped out of the geological timeline without any warning
